New Algorithms for Fast Discovery of Association Rules
- In 3rd Intl. Conf. on Knowledge Discovery and Data Mining
, 1997
"... Association rule discovery has emerged as an important problem in knowledge discovery and data mining. The association mining task consists of identifying the frequent itemsets, and then forming conditional implication rules among them. In this paper we present efficient algorithms for the discovery ..."

Achievement goals in the classroom: Students’ learning strategies and motivation processes
- Journal of Educational Psychology
, 1988
"... We studied how specific motivational processes are related to the salience of mastery and performance goals in actual classroom settings. One hundred seventy-six students attending a junior high/high school for academically advanced students were randomly selected from one of their classes and respo ..."

students, the motivational processes that are associated with these different goals, and the conditions that elicit them. These goal orientations have been contrasted as task involved versus ego involved (Maehr, 1983;Maehr&Nicholls, 1980;Nicholls, 1979, 1984; see also deCharms, 1968, 1976), as learning
Efficient Estimation of Average Treatment Effects Using the Estimated Propensity Score
, 2000
"... We are interested in estimating the average effect of a binary treatment on a scalar outcome. If assignment to the treatment is independent of the potential outcomes given pretreatment variables, biases associated with simple treatment-control average comparisons can be removed by adjusting for diff ..."

Effective Compiler Support for Predicated Execution Using the Hyperblock
, 1992
"... Predicated execution is an effective technique for dealing with conditional branches in application programs. However, there are several problems associated with conventional compiler support for predicated execution. First, all paths of control are combined into a single path regardless of their ex ..."

Segmentation using eigenvectors: A unifying view
- In ICCV
, 1999
"... Automatic grouping and segmentation of images remains a challenging problem in computer vision. Recently, a number of authors have demonstrated good performance on this task using methods that are based on eigenvectors of the a nity matrix. These approaches are extremely attractive in that they are ..."

. In many cases, this is done by associating with each pixel a feature vector (e.g. color, motion, texture, position) and using a clustering or grouping algorithm on these feature vectors. Perhaps the cleanest approach to segmenting points in feature space is based on mixture models in which one assumes
A model for Pavlovian learning: Variations in the effectiveness of conditioned but not of unconditioned stimuli
- Psychological Review
, 1980
"... Several formal models of excitatory classical conditioning are reviewed. It is suggested that a central problem for all of them is the explanation of cases in which learning does not occur in spite of the fact that the conditioned stimulus is a signal for the reinforcer. We propose a new model that ..."

that deals with this problem by specifying that certain procedures cause a conditioned stimulus (CS) to lose effectiveness; in particular, we argue that a CS will lose associability when its consequences are accurately predicted. In contrast to other current models, the effectiveness of the reinforcer
Scalp distribution of event-related potentials: An ambiguity associated with analysis of variance models
- Electroencephalography and Clinical Neurophysiology
, 1985
"... An important question in event-related poten-tial (ERP) experiments i whether ERP scalp dis-tributions differ between experimental conditions, subject groups, or components. Scalp distributions are an important criterion for identifying ERP components (for discussion, see Donchin et al. 1978; Picton ..."

Transition Network Grammars for Natural Language Analysis
- COMPUTATIONAL LINGUISTICS, D.G. BOBROW, EDITOR

Perceived organizational support: A review of the literature
- Journal of Applied Psychology
, 2002

The authors reviewed more than 70 studies concerning employees ’ general belief that their work organization values their contribution and cares about their well-being (perceived organizational support; POS). A meta-analysis indicated that 3 major categories of beneficial treatment received by emplo ..."

POS, in turn, was related to outcomes favorable to employees (e.g., job satisfaction, positive mood) and the organization (e.g., affective commitment, performance, and lessened
